What people bring us, and how we handle it.

在树冠变色之前看见胁迫

NDVI 的变化要等到树冠干枯到无法挽救的数周之后。

冠层含水量先于颜色发生变化,短波红外测量直接读取这一水分,在干预仍有意义时标记正在失水的林分。

对照边界核查采伐

单株采伐基本不破坏上层冠层,粗分辨率影像完全看不见。

亚米级短波红外解混提取采伐剩余物、集材道与楞场。让 Lisaris 按计划运行特许经营区,它会标记发生变化的日期。从不破顶的采伐依然不可见。

复杂地形中的燃烧强度

宽波段指数会把阴影中未燃的树读成地面焦炭,在陡坡上夸大强度。

差分归一化燃烧比,并在其下解混焦炭、灰烬、土壤与绿色组分,部分燃烧的像元读作部分燃烧。

01

网格处理

Reprojection onto a common grid, never resampling

场景重投影到同一网格而非重采样,这条规则由每次构建的静态测试强制执行。

02

叶片水分谱带深度

Water absorption depth taken against a dry-matter shoulder

水吸收对照干物质肩部测量,叶片结构无法伪装成水分。

03

林分内相对变化

Stand-relative change, not absolute water content

报告林分内、两期之间水吸收深度的变化,而非绝对含水量。

04

您将获得

GeoJSON stand polygons with evaluable fraction per stand

GeoJSON 林分多边形,每个都注明其可评估像元的比例。

FREQUENTLY ASKED QUESTIONS

Questions we get asked about this sector.

随着气孔关闭、膨压丧失,叶片含水量下降,水吸收特征随之变化,早于叶绿素分解出现可见的黄化。测量直接支持的是林分内相对变化,图层也就如此报告。
